Resumen
We present an overview on the use of disposable electrochemical biosensors for diagnostics, focusing on the applications of these devices as immunosensors and DNA sensors in the point-of-care diagnostics. Analytical biosensors have emerged as efficient alternatives for the detection of innumerous diseases, because of their high specificity and the convenience of detecting the electrochemical signals produced by the presence of an analyte using a portable equipment. This review highlights the recently developed strategies toward immobilization of different biological molecules on disposable electrodes such as carbon nanotubes and metal nanoparticles. In the course of the review, we first introduced the disposable biosensors, followed by an overview of the immunosensors, and discussed the applications of DNA sensors and disposable biosensors in point-of-care diagnostics. We also have evaluated the prospects and future applications of these devices in the field of biomedical research.
